Material facts

Loose-fill fiberglass at a glance (U.S. DOE data)

Settled R-value per inchAbout R-2.2 to R-2.7Lower per inch than cellulose, so it is installed deeper.
Depth for R-38About 14 to 17 inchesAsk the installer for the bag coverage chart depth.
Settling over timeAbout 2 to 4 percentLess settling than loose-fill cellulose.
WeightLighter than celluloseOK over 1/2 in. drywall on 24 in. framing, per DOE data.
MoistureNot permanently damaged if saturatedStill find and fix the leak source first.

Blown-in fiberglass vs batts

ENERGY STAR lists loose-fill (blown-in) insulation as suited to unfinished attic floors and hard-to-reach places, and batts as suited to unfinished attic floors with standard joist spacing and few obstructions. Many Ocala attics have trusses, ducts, and wiring, which is why blown-in is common for retrofits. See blown-in insulation in Ocala.

Install quality matters

DOE's Building America guidance warns against "fluffing": installing loose fill below the manufacturer's minimum density, which uses fewer bags and lets air move through the insulation. Fiberglass is easier to fluff than cellulose. Ask for the bag count and the installed depth, and plan air sealing first.

Fiberglass or cellulose?

Both reach the same R-value when installed to the right depth. Compare on the cellulose insulation page or the spray foam vs fiberglass guide.

Local questions

Questions homeowners ask before requesting a quote

How much blown-in fiberglass do I need for R-38?

DOE data puts it at roughly 14 to 17 inches of settled loose-fill fiberglass. The manufacturer's bag chart sets the exact depth and bag count.

Is fiberglass or cellulose better for an Ocala attic?

Both can reach the target R-value. Fiberglass is lighter and settles less; cellulose has a higher R-value per inch and slows air movement better. A provider can recommend based on your attic.

Can fiberglass go on top of existing insulation?

Often, if the existing insulation is dry and clean. Wet or contaminated material should be removed first.
